My Nexus 6P's battery is draining TOO FAST. It just stays for 5 hours and 70% battery is drained by only Android OS and Android System

This has primarily happened after moving to Android 7

Please help what settings can help with this.

I recently started experiencing this problem as well. The most annoying part of the problem was that the phone would shut down at fairly high battery percentages, like 14%, and then when I restarted it would be at like 2%, so clearly the battery calibration had gotten out of kilter.

I performed a full FDR last weekend, which did help overall battery life, but then I still experienced that early shutdown. So, I read somewhere that letting the phone charge from totally dead back to 100% before rebooting it would recalibrate the battery. I tried that earlier this week, and since then I can now get a full 15-16 hours from the phone with more than 20% battery to spare, and if I do need to run it down, it will get to single digits without spontaneously restarting.

I know that some will respond to say that you should never let your battery get below like 40% before charging, but most days that's just not feasible for me. I need the battery to give me a full day, then I plug it in at night to charge while I sleep.

Don't feel like you're alone I am also seeing the battery drain quicker than I'd expected t due to android os

There could be a rouge app causing it to happen, if you have gsam get rid of it! It was killing my battery. Once I uninstalled it, everything normalized.

Mine appears to have been almost all Bluetooth, I had the same deal, after upgrading.

Over on the Google support forums a bunch of people where talking about disabling BT when not in-use, and how it helped, and sure enough, this pretty much solved it for me.

It's a pain, because I recently moved to a 6P, from having WinPhone forever, where you have to disable BT whenever not in use. Here I was on MM, digging being able to just connect to my BT devices without hassle, and then I upgraded to 7.0.
Hopefully Google will come out with a fix, there were a couple of Google people who acknowledged there was a problem, over in the support forums...

Yesterday I enrolled my phone for the Android BETA program, and the OTA for 7.1.1 developer preview immediately came up and I installed. As soon as it completed I did a system cache wipe just to make sure I was clean going forward. The phone has been absolutely STELLAR as far as battery life goes, and bluetooth has been perfect.

This morning I charged the phone to full, pulled it off the charger at 7am and went to work. It was a busy morning, so my phone just sat on the desk without me touching it... although it did receive emails, and 2 text messages. at 10:30am I picked it up and the phone was at 99%. The idle drain is amazing now.

So for you guys suffering bad battery life with 7.0 or having bluetooth issues, I encourage you to bite the bullet and get the 7.1.1 preview.

I'm on 7.1.1 and the battery has not changed since I installed 7.0. when you say system cache wipe, you mean like the full clean install or just from the storage cache data section ?

Did you unenroll from developer preview? I was contemplating signing up to get security updates but don't want phone to be wiped out. I signed up for developer preview to receive Nougat update bc I wasn't receiving it..

Picture didn't attach.. seems to be a glitch with app. Not uploading pictures. Wtf! !!

I'm talking about turning off phone, booting into recovery mode and wiping from there. Just Google cache wipe for 6p to get the full steps. It insures a cleaner system.

However, whenever I go up a major update (1gb+) I do a factory data reset followed by a cache wipe.

If you're still having issues with 7.1.1 I would do the factory reset followed by the cache wipe. Then install your apps.

Amen! What is the point of having a huge battery if you are only supposed to use 60% of it before charging?

[fju2112]

What's gsam?

[B. Diddy]

GSam is GSam Battery Monitor.

The recommendation to recharge when the battery hits 30-40% is a general rule of thumb, if you want to prolong the battery's overall lifespan as much as you can. If you routinely drain it deeply, you'll find that the battery starts deteriorating sooner. But it's a general rule -- it doesn't mean that the occasional deep drain will kill the battery immediately.

I always think ppl who report bad battery life leave on Bluetooth and GPS all day. Both will kill batteries fast but high accuracy GPS is a real killer

[brutos08]

I pretty much given up on good battery life on the 6P since Nougat as no matter how many apps what type of apps nothing really changes it's still the same very poor battery life and had a few instances where it switches off early and random reboots.

But if we haven't changed our habits prior to this update, why is this a legit claim? If my battery lasted about 20% more pre 7.1 with BT and GPS on all day, why should I turn it off it?

4 months later and the battery hasn't improved, I only get around 2 hrs screen on with 17-20 hrs use (that's barely any use, texts and some reading).

Pixel users report fantastic battery life so I guess google optimized their phone perfectly while ours is left lingering. It's not the worst battery life I've experienced but it's a definite drop compared to prior.

I had wondered if the later builds caused poor performance.. then I did some more digging. I loaded up an app that monitors my battery capacity, rather than looking at screen times, etc.

Turns out that my 14 month old 6P's battery had degraded a bit... I only had an effective capacity of about 3000mah (which is normal and expected for a battery that old and in constant use).

I found a place that would replace it (which was a bit of a challenge)... And now I've gained a good 90 minutes of screen time back.

So I'm not saying it's the solution for everyone's battery issues, but if you have an older one, it's a possibility.

That very one. I'm not 100% sure it's totally accurate, but their methodology is spot on.

I leave Bluetooth and GPS on all day. My GPS is set for high accuracy. My battery life has been fine. I routinely use 3-4 hours of screen time a day (mostly on the train to/from work) and never have less than 50% left at the end of the day.

[The Captain 105]

I just recently started to experience this... no new apps, no new habbits... my battery easily made it through half the day without a recharge before... this last couple months it's been dying in after two/three hours off a full charge. It'll just die when the battery gets down to around a 15% - 30% charge...

[seventy4burban]

My battery was terrible as well. It would die when battery saver should be coming on. I just replaced the battery and right now its at 11% and says an hour and 38 minutes remaining. Never would have had that before. Haven't fully charged it up yet so tomorrow will be a interesting test.

Replacing the battery worked like new for me. heavy daily use I'm getting 10 hours a day. With light use, many more hours, but I'm always a heavy user.

How the heck do you replace the battery in the 6p?
